干旱是限制植物种植分布、生长发育以及作物产量的主要非生物胁迫因素之一。棉花是重要的经济作物,新疆是中国棉花种植的主要地区,占全国棉花种植面积80%以上。干旱胁迫是影响新疆棉花生产重要的非生物胁迫因素。挖掘关键抗旱基因,揭示棉花对干旱胁迫的应答机制,培育耐逆新材料和新品种,不仅具有重要的科学研究价值,也是服务棉花可持续发展的重要保障。NAC转录因子在植物非生物胁迫信号中起着重要的转录调控作用。然而,...
The collapse of the Hittite Empire in the Late Bronze Age has been blamed on various factors, from war with other territories to internal strife. Now, an interdisciplinary collaboration used tree ring...
生长素在植物的正常生长发育中起着至关重要的作用。TAA/YUCCA基因家族编码色氨酸氨基转移酶(tryptophan aminotransferase),是生长素合成的关键酶。然而,棉花中YUCCA(YUC)基因家族尚未见报道。为了揭示YUC基因在棉花中的功能,我们系统地鉴定了五个棉种中的YUC基因家族,包括成员分析、特征描述、基因组内复制和共线关系。转录组学分析表明,GhYUCs参与了棉花的非生...
The Millennium Drought (southeastern Australia) provided a natural experiment to challenge the assumption that watershed streamflow always recovers from drought.
With climate change heating the globe, drought more frequently impacts the reproduction and survival of many animal species.New U.S. National Science Foundation-funded research by University...
You might expect that plants hoping to thrive in California's boom-or-bust rain cycle would choose to set down roots in a place that can store lots of water underground to last through drought years.B...
Drought intensifies stress on the water resource which is already in a critical condition due to rapid urbanization and population growth thus, affecting people, economy, and environment. The drought ...
India being an agrarian nation widely depends upon rainfall for its agricultural productivity. The failure of rainfall and hence shortfall of productivity badly affects national economy. With an intri...
Change in soil moisture regime is highly relevant for agricultural drought, which can be best analyzed in terms of Soil Moisture Deficit Index (SMDI). A macroscale hydrological model Variable Infiltra...
Drought has become a problem that is universally faced by global terrestrial ecosystems. Northeast China is located in a region sensitive to global climate changes, and one of the main impacts of clim...
Drought-stricken areas anxiously await the arrival of rain. Full recovery of the ecosystem, however, can extend long past the first rain drops on thirsty ground.According to a study published August 1...
The next mega-droughts and subsequent active wildfire seasons for the western U.S. might be predictable a full year in advance, extending well beyond the current seasonal forecast and helping segments...
A study led by UC Santa Cruz researchers has found that drought dramatically increases the severity of West Nile virus epidemics in the United States, although populations affected by large outbreaks ...
Cold snaps in sub-tropical ecosystems, life under cities in soils, drought in rainforests, and desertification in grasslands are among the topics featured at the 2016 meeting of the Ecological Society...
Drought left 225 million trees dead in the U.S. Southwest in 2002. Nine years later, it killed 300 million trees in Texas. This past year, 12 million trees died in California.Drought left 225 million ...
